CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of U.S. Pat. No. ______, currentlyU.S. application Ser. No. 11/742,264, entitled “Adaptive Training Systemwith Aerial Mobility System”, filed on Apr. 30, 2007, and allowed onJul. 23, 2009, which application is hereby incorporated by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to training systems, and inparticular to adaptive training systems including a mobile unit that isair-based.

2. Description of Related Art

When an athlete trains for a particular activity they may choose tofocus on their weaknesses as well as their strengths. Many times, anathlete that is well rounded has an advantage over other competitorsthat are only strong in one particular aspect of an athletic activity orsport. Therefore, in selecting a workout routine or program, an athlete(or the athlete's coach) may adapt a given routine or program so that itstresses weaknesses in the athlete's performance.

In many situations, the athlete's weaknesses may not be well known. Insuch situations it may be useful to have a training system that isconfigured to evaluate the athlete's performance. Based on thisevaluation, a coach or the athlete may make modifications to thetraining method in an attempt to stress the athlete's weaknessesaccording to the reported performance.

Several methods and/or devices configured to train an athlete have beenpreviously proposed, including mechanisms for measuring various aspectsof the athlete's performance. Davidson (U.S. patent number 2004/0219498)teaches a training system consisting of a computer and a trainer and/ortrainee garment configured to accurately track body movements of thewearer. These body movements are then compared to reference bodymovements and a report is generated with the results of the comparison.In some cases, the reference body movements are generated by a coach orother trainer. For example, a trainee may wish to learn the ideal golfswing, and by comparing their body movements of the swing with thepre-programmed body movements of a golf-pro's swing, they may learnweaknesses in their swing and adapt it to conform closer to thereference swing.

A drawback of the Davidson design is the cumbersome nature of thetrainer/trainee garments. In many cases, such garments could prohibit afull range of motion, decreasing the utility of the training system insuch circumstances. Furthermore, the Davidson design is primarilyintended to be used as a tool for comparing an athlete's body movementswith the body movements of a secondary party (a coach, trainer, etc.).The Davidson design does not provide a straightforward means ofcomparing various aspects of the athlete's performance with one another.Finally, the Davidson design does not provide a clear method forfocusing on and stressing weaknesses in the athlete's performance, andespecially not in an automated manner.

Bachman (U.S. Pat. No. 5,938,564) teaches a track runner pacing device,including a running track. In the Bachman design, a pacer housing isadapted to move around the running track. The Bachman design alsoincorporates a control mechanism that effects the movement of the pacerhousing about the track at a speed calculated from a distance and a timeentered into the control means by a user.

The Bachman design includes several drawbacks. Bachman teaches the useof a pacer housing with a simple rounded track. Although the athletemust turn slightly in order to make their way fully around the track,this training device is generally configured only to stress linear speedand pacing. The Bachman design would not be well suited for trainingathlete's in sports where one is not confined to a track. In football,for example, an athlete must perform ‘cut-moves’ and general lateraltranslations that could not be modeled using the Bachman design.Additionally, using the Bachman design, an athlete (or a coach) mustprogram information that is used to calculate a predefined pacing speedfor the pacer housing. The Bachman design lacks a provision forautomatically adapting the pacer housing speed to stress weaknesses inthe athlete's performance.

Dassler (U.S. Pat. No. 4,703,445) teaches an athletic shoe for runningand a process for providing an exchange of information concerning movingsequences. In the Dassler design, a transmitter is housed in a freespace of the sole of the shoe, which, via a sensor in the sole, can emitat least one output signal. Following the transmission of the signal, aremote receiver receives the emissions. Also, a secondary transmitterand sensor may be associated with a second shoe, whose emissions arealso received by the remote receiver either directly or indirectly viathe first transmitter. The remote receiver may be linked with acomputer. Using the information collected from these emissions, thecomputer may determine the distance between the first and the secondshoes, on the basis of the delay between the receipt by the remotereceiver of the directly and indirectly received emissions, as well asother characteristic length values related to stride rate or length.Based on this computed information, which may be stored and lateranalyzed, conclusions may be drawn with respect to further trainingphases or sequences and possibly different training phases or sequences.

A drawback of the Dassler design is that it is configured to assess onlyinformation related to stride length and/or running speed. The Dasslerdesign lacks provisions for locating the runner along a given trajectoryor path, and determining performance aspects of the athlete associatedwith lateral motions, banking motions, and starting and/or stoppingmotions. Furthermore, while the Dassler design provides tools foranalyzing an athlete's running style, it does not directly provide theathlete with a means for stressing particular weaknesses in theirrunning style. Instead, the athlete and/or coach must analyze theacquired running data and make their own judgments about new trainingregiments.

In some training exercises, it may be useful to have a training devicethat can sense the location of the athlete and either move away from, ortowards the athlete. In the prior art, devices with such features areusually associated with robots. Several such devices have beenpreviously proposed.

Oohashi (U.S. patent number 2006/0126918) teaches a robot provided witha target object detection apparatus. The target object detectionapparatus includes a wireless tag worn by the target object and a cameraused for recording image information. Oohashi teaches the use of an RFIDtag, in particular, with the target object detection apparatus. Oohashialso teaches the use of an image processor to interpret images recordedby the camera. The camera is configured to take images of the targetobject's face, and using the image processor, determine, with someassociated probability, the identity of the target object.

A drawback to the Oohashi design is that it lacks provisions for use asan athletic training device. Although the robot does include legs formoving, Oohashi does not teach a robot that can run or move at speedsuseful for athletic training. Furthermore, the RFID tag is used tosignal the target objects identity, but not as a means of location. As aresult, the Oohashi design lacks provisions for determining precisedistances between the target object and the robot which serves as thetarget object detection apparatus.

Okamoto (U.S. patent number 2006/0106496) teaches a method ofcontrolling the movement of a mobile robot. This method is intended toprovide safe and appropriate accompanying behavior to follow anaccompanied target. The Okamoto design includes provisions for detectingthe position of the target. The Okamoto design also teaches a method forcontrolling the robot to walk along a path that is parallel to themoving direction of the accompanied target. The mobile robot includes arobot body, wheels for moving the robot, and a measurement apparatusthat detects the position and velocity of the robot body and acalculator that calculates a path for accompanying the accompaniedtarget based on measurements made by the measurement apparatus.

The Okamoto design lacks provisions that would allow its use as anathletic training device. Okamoto teaches a robot that moves in parallelwith the target, while a proper training device may require that therobot move ahead of, behind, or in various other directions with respectto the athlete or target. Furthermore, while the Okamoto design includesa measurement apparatus for detecting the speed and location of thetarget, there are no provisions for storing and analyzing thesemeasurements in order to examine trends in the targets motion as wouldbe useful in a training apparatus.

Hart (U.S. Pat. No. 5,083,968) teaches an interactive toy that iscapable of detecting and tracking any nearby heat source such as a humanbody. The Hart device is further able to move to interact with the heatsource, including chasing the heat source, or running away from the heatsource. The Hart device also includes sensors to detect unheated objectsin its path and may move to avoid these objects.

Although the Hart design does provide a device that may chase or bechased, there are several limitations that limits its use as an athletictraining device. Hart does not teach the use of instruments intended tomeasure the position and/or location of a human. Additionally, Hartfails to teach a mechanism by which the interactive toy can move atspeeds relevant to athletic training, including speeds associated withrunning. Also, the Hart design lacks provisions for adapting to themovements of the human.

The prior art has many shortcomings, as previously discussed. There is aneed in the art for a training device or system that may solve many ofthe problems not addressed by the prior art. In particular, there is aneed in the art for an athletic training system that includes a devicethat can interact with an athlete by chasing, being chased, or othersimilar activities at speeds that are relevant to athletic activities.Furthermore, there is a need in the art for an athletic training systemthat includes provisions for analyzing the movements of the athlete,determining weaknesses in the athlete's movements, and automaticallyadapts its own motion to yield new training routines that stress theathlete's weaknesses.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIGS. 1-2 are a preferred embodiment of training system 100. Trainingsystem 100 preferably includes practice field 106. The term ‘practicefield’, as used throughout this detailed description, refers to any typeof field, court, or generally open space that may be used for trainingactivities. Examples of practice fields include, but are not limited to,football fields, soccer pitches or fields, lacrosse fields, basketballcourts, as well as other types of fields and/or courts. Additionally,any open space that may be used for training activities such as thosedescribed throughout this detailed description may also be consideredpractice fields. For the purposes of clarity, practice field 106 isshown here as a football field.

Preferably, training system 100 may also include athlete 102. The termathlete is intended to include both professional athletes and amateurathletes. Generally, athlete 102 may be any person wishing to take partin an athletic training activity. Therefore, the term athlete, as usedthroughout this detailed discussion and in the claims, refers to anyuser of training system 100.

Training system 100 also preferably includes mobile unit 104. The term‘mobile unit’ refers to any mechanical device with mobile capabilities,intended for use with training system 100. In some embodiments, mobileunit 104 may be configured to move around practice field 106. Inparticular, it is preferable that mobile unit 104 may be configured toaccomplish the task of running away from athlete 102 and/or chasingathlete 102. In some embodiments, mobile unit 104 may be a robot. Inother embodiments, mobile unit 104 may be more similar to a small car,cart or similar vehicle.

In the current embodiment, mobile unit 104 is seen to have a simpleshape and/or design. In some embodiments, mobile unit 104 may have anappearance that is similar to a remote controlled car or other vehicle.In some embodiments, mobile unit 104 may have a ‘rover’-like appearance.It should be emphasized that the shape and design of mobile unit 104shown in the Figures is only intended as an exemplary embodiment.Generally, mobile unit 104 may have any size, shape and/or design. Forexample, in another embodiment, mobile unit 104 may be human-like,including legs, arms, a head, as well as other human-like features. Instill other embodiments, mobile unit 104 may be configured to look likean animal, such as animals associated with ‘chasing’, like rabbits, catsand other kinds of animals.

In still other embodiments, mobile unit 104 may include provisions thatmimic characteristics of a real athlete. For example, as seen in FIG. 3,in some embodiments mobile unit 104 may include dummy 300. Using dummy300, athlete 102 may feel more natural attempting to chase or ‘cover’mobile unit 104. In other embodiments, other decorative features may beapplied to mobile unit 104.

Preferably, training system 100 includes provisions for training anathlete with respect to various athletic skills that are important for astrong performance in many sports. Examples of these athletic skillsinclude, but are not limited to linear speed, lateral speed, leftturning speed, right turning speed, starting acceleration, mid-strideacceleration, deceleration as well as other capabilities. For example, arunning back in football must have good lateral speed in order to avoidtackles in addition to having good linear speed in order to move theball down the field. Therefore, it may be important to have a trainingsystem available to the athlete that trains them with special emphasisplaced on one or more of these athletic skills.

As seen in FIGS. 1 and 2, training system 100 is preferably configuredso that athlete 102 chases mobile unit 104 on practice field 106.Preferably, during this chasing activity, mobile unit 104 is alwaysmoving in a way to avoid being caught by athlete 102. As mobile unit 104constantly changes direction and/or speed, athlete 102 must adjust tothe new direction and speed in an attempt to catch mobile unit 104.Preferably, mobile unit 104 moves in a way so that, as athlete 102follows mobile unit 104, athlete 102 is moving linearly, laterally,accelerating and decelerating over the course of a training session.

FIG. 4 is a schematic diagram of several devices, resources and/orprovisions that are associated with mobile unit 104 and athlete 102.Preferably, mobile unit 104 may include control unit 402. Control unit402 may include a number of ports that facilitate the input and outputof information and power. The term “port” means any interface or sharedboundary between two conductors. In some cases, ports can facilitate theinsertion and removal of conductors. Examples of these types of portsinclude mechanical connectors. In other cases, ports are interfaces thatgenerally do not provide easy insertion or removal. Examples of thesetypes of ports include soldering or electron traces on circuit boards.

All of the following ports and provisions associated with control unit402 are optional. Some embodiments may include a given port orprovision, while others may exclude it. The following descriptiondiscloses many of the possible parts and provisions that can be used,however, it should be kept in mind that not every part or provision mustbe used or included in a given embodiment.

In the exemplary embodiment shown in FIG. 4, control unit402 includes a local wireless network antenna port 446 that is designedto communicate with a local wireless network antenna 448, which in turn,is designed to communicate wirelessly with any wireless device.

Control unit 402 can also include a number of items that facilitatehuman interaction with mobile unit 104. To receive vocal informationfrom a user, control unit 402 can include a microphone port 432 that iscapable of communicating with a microphone 434. Control unit 402 canalso include an audio port 436 that is designed to send audioinformation to one or more speakers 438 or audio devices. These audiodevices can include preamplifiers, amplifiers and/or crossovers. In someembodiments, microphone port 432 and audio port 436 are conductorsassociated with a single physical connector. For example, microphoneport 432 and audio port 436 can be female conductors of a multi-channelcoaxial plug, like a standard 2.5 mm headset plug.

Preferably, control unit 402 may be associated with various opticalsensors that may be configured to monitor the location or trajectory ofathlete 102. These various optical sensors may also be used to helpdetermine the location of mobile unit 104 on practice field 106, as wellas avoid obstacles and monitor general conditions of the environment.Control unit 402 can include optical port 460 that is designed tocommunicate with optical device 462. In some embodiments, optical device462 may be one or more video cameras associated with various sides ofmobile unit 104. For example, mobile unit 104 may include a video camerafor rearward viewing that may be especially useful in tracking athlete102 as athlete 102 chases behind mobile unit 104. Mobile until 104 mayalso include additional video cameras along a front side, as well asalong the left and right side, and even a downward looking camera, alldesigned to give mobile unit 104 full view of athlete 102, theenvironment, and also to enable mobile unit 104 to avoid any obstacleson practice field 106. In other embodiments, optical device 462 may bean infrared camera configured to sense heat sources such as athlete 102.This infrared configuration may be useful in dark conditions such as atnight.

In some embodiments, control unit 402 may include provisions such as aninteractive panel that may facilitate in programming, or accessinginformation from, mobile unit 104. Control unit 402 may be associatedwith display panel port 470, designed to communicate with display device472. To receive input from a user, control unit 402 can include an inputport 474. Input port 474 can communicate with input device 476. In someembodiments, display device 472 can also receive input from a user. Insome embodiments, display device 472 includes a touch screen that canreceive input and in other embodiments, display device 472 includes anumber of buttons that can receive input. In some embodiments, displaydevice 472 includes both a touch screen and buttons.

A power port 476 can connect control unit 402 to power supply 480.Examples of specific types of power supplies that may be used withmobile unit 104 include, but are not limited to, standard batteries,rechargeable batteries, engines, photochemical power sources, hybridpower sources and other types of power sources. In other embodiments,power supply 480 may be a remote power source connected to mobile unit104 using a wire or similar electrical conductor. Generally, the type ofpower source used will vary.

Mobile unit 104 can also include data storage provisions including oneor more databases or similar data storage devices. Preferably, controlunit 402 is in communication with at least one database 490 via databaseport 405. Database 490 can be any kind of data storage device, includingbut not limited magnetic, optical, magneto-optical, and/or memory,including volatile memory and non-volatile memory. In some embodiments,database 490 is integral with control unit 402 and in other embodiments,database 490 is separate from control unit 402 and communicates withcontrol unit 402. In some embodiments, for example, database 490 may belocated outside of mobile unit, and accessed remotely via any knownwired or wireless methods.

In some embodiments, all or most of the items shown in FIG. 4 are housedin a single case or unit. In other embodiments, the various items shownin FIG. 4 are not housed at a single physical location, but instead, aredistributed throughout mobile unit 104 and communicate with one anothervia known wired or wireless methods. In general, any of the items shownhere may be physically located outside of mobile unit 104, and remotelyaccess via any of the communication methods discussed here forinformation transfer.

Mobile unit 104 may include provisions for moving. Preferably, mobileunit 104 includes mobility system 408. Mobility system 408 may be incommunication with control unit 402 via mobility system port 409. Inthis embodiment, mobility system 408 is a set of wheels. However, inother embodiments, mobility system 408 may be a mechanism other thanwheels. For example, robots with legs that can move around havepreviously been disclosed. The reader is referred to U.S. Pat. Nos.7,142,946; 7,076,338; 7,072,740; 7,061,200; 7,054,718; 7,053,577; and7,031,806, for more information, the entirety of which are incorporatedhere by reference. In some embodiments, mobility system 408 may includetwo, three, four, or more legs. Additionally, mobility system 408 maycomprise a set of tracks similar to those found in many tanks.

Preferably, mobile unit 104 has the ability to attain speeds associatedwith high performance athletes. Because mobile unit 104 is intended tomimic motions of various athletes including a wide receiver, forexample, realistic training of athlete 102 by mobile unit 104 can onlybe accomplished if mobile unit 104 is able to move with the same speedas a typical, or even elite, wide receiver. Generally, the fastest ahuman can run is in the range of 10-12 meters per second, and this isgenerally for very short periods of time. Although it is unlikely thatan average wide receiver or other athletes will run at these speeds,especially for any extended period of time, the value of 13 meters persecond may serve as an upper bound on the range of speeds which mobileunit 104 may be expected to achieve. In other words, it is preferablethat mobility system 408 include provisions for propelling mobile unit104 at any speed between 0 and 13 meters per second.

Training system 100 may also include provisions for monitoring athlete102 during a training session. Preferably, this monitoring is performedby mobile unit 104. In some embodiments, athlete 102 may be associatedwith sensor system 492 designed to transmit and/or receive informationbetween athlete 102 and mobile unit 104. In this embodiment, sensorsystem 492 includes sensor harness 493, including front sensor 494.Sensor system 492 also includes footwear sensor 495 that may be disposedwithin any part of article of footwear 496.

Front sensor 494 and footwear sensor 495 may be configured to transmitand/or receive information related to GPS data as well as RFID data. Forexample, sensors 494 and 495 may be configured to receive GPSinformation regarding the location of athlete 102 from GPS system 481and then transmit this information to mobile unit 104. In anotherexample, practice field 106 may include a network of RFID tagsconfigured to transmit location related information. As athlete 102moves through the network of RFID tags, sensors 494 and 495 may receivethis location information and transmit it to mobile unit 104.

Additionally, front sensor 494 and footwear sensor 495 may be configuredto transmit any signal that may be received by mobile unit 104 using oneof the various receiving devices previously discussed. In some cases, bytransmitting a simple signal at any desired frequency, mobile unit 104may use this transmitted information to determine the location ofathlete 102 on practice field 106. In some cases, optical informationreceived by optical device 462 may be used in conjunction with a simpletransmission signal to more accurately determine the location of athlete102.

The configuration of sensor system 492 shown in this embodiment is onlyintended to illustrate the various types and locations of sensors thatmay be associated with athlete 102. In other embodiments, more than twosensors may be used, or only a single sensor may be used. Additionally,the location of sensors comprising sensor system 492 may vary from thepreferred embodiment.

Mobile unit 104 may also be associated with computer 482. The term‘computer’ refers to any device including a central processing unit,some kind of memory, a user interface and mechanisms for input/output.Computer 482 can be a portable computer, for example, a laptop, notebookor Personal Data Assistant (PDA). Computer 482 can include a database,generally residing in a mass storage device like a hard disk drive or anoptical storage device. The term “computer” refers to the computingresources of a single computer, a portion of the computing resources ofa single computer, and/or two or more computers in communication withone another, also any of these resources can be operated by one or morehuman users. In an exemplary embodiment, computer 482 includes apersonal computer.

In some embodiments, mobile unit 104 may communicate with computer 482via a wireless network, including but not limited to any broadbandwireless access network or a high bandwidth packet switched networkusing, for example, any one of the following standards: IEEE 802.11a,IEEE 802.11b, and/or IEEE 802.11g, commonly referred to as WiFi, IEEE802.16a, referred to as WiMAX. Computer 482 and mobile unit 104 may alsocommunicate via the Bluetooth protocol.

Preferably, computer 482 may assist control unit 402 in processingand/or storing information gathered by mobile unit 104. In someembodiments, computer 482 may be used as an interface to program mobileunit 104 as well as receive information from mobile unit 104 regardingthe performance of athlete 102.

In some embodiments, mobile unit 104 may be programmed to follow aparticular path for training athlete 102, as designated by a trainer orcoach. FIG. 5 is a flow diagram of a preferred system and method forcreating a training path. The following steps are preferably implementedby a coach or trainer that has knowledge of the training needs ofathlete 102. However, in other embodiments, these steps may beimplemented by athlete 102 or anyone else.

During a first step 502, trainer 500 preferably creates and/or receivesa training regiment for athlete 102. In some embodiments, trainer 500may design a training regiment using general knowledge of athlete 102 aswell as other information. In other embodiments, trainer 500 may receivea training regiment from an outside source, such as a book, the internetor another trainer. Preferably, trainer 500 then proceeds to create apath for mobile unit 104 that is based on the training regiment, duringa second step 504. For example, if the training regiment is a set ofsprinting exercises and a set of lateral running exercises, trainer 500may create a path for mobile unit 104 that incorporates long linearpaths and several lateral paths.

In another example, shown in FIG. 6, trainer 500 has created path 600 toinclude first linear portions 601, second linear portion 602, thirdlinear portion 603, lateral portion 604, as well as banking portion 605and fourth linear portion 606. Additionally, path 600 is configured toinclude several sharp turns 610. Using this training configuration,athlete 102 may be trained in linear speed as well as bank speed andturning speed.

In some embodiments, path 600 may be created using a simple graphicalprogram that is preferably configured to run on computer 482 and betransmitted to mobile unit 104. In other embodiments, trainer 500 maydesignate path 600 using display device 472 and/or input device 476 ofmobile unit 104. During a third, and final, step 506, trainer 500 maysubmit path 600 to mobile unit 104. In some embodiments this may beachieved by using computer 482 to submit path 600 to mobile unit 104. Incases where trainer 500 is designing path 600 using display device 472and/or input device 476 of mobile unit 104, trainer 500 may press a‘submit’ button to finalize the design.

It should be understood that FIG. 6 represents a possible embodiment ofpath 600 as created by trainer 500. In some embodiments, path 600 may besubmitted to mobile unit 104 with additional information. For example,information regarding field boundaries, intermediate markers, preferredspeeds, as well as other preferences associated with the envisionedtraining route may be submitted. For example, in some embodiments,trainer 500 may submit additional instructions that mobile unit 104should pause for 5 seconds at halfway mark 620. This command mayfacilitate training athlete 102 in acceleration and deceleration.Preferably, mobile unit 104 is configured to receive additional types ofinformation.

FIG. 7 is a flow diagram of a preferred embodiment of the processesassociated with mobile unit 104, once a training session has started.Preferably, mobile unit 104 receives path information during step 702,after it has been submitted to mobile unit 104 by trainer 500. It shouldbe understood that in other embodiments, path information could comefrom elsewhere besides trainer 500. In some embodiments, a predefinedpath could be selected by mobile unit 104, either randomly or on thebasis of some input received at input device 476. For example, mobileunit 104 could be preprogrammed by a manufacturer with multiple trainingpaths that are configured to be used on fields of various sizes.

Next, the current location of mobile unit 104 may be determined duringstep 704. This information may be received by GPS, preprogrammedcoordinates, or using another method. In some embodiments, the currentlocation of mobile system 104 may be stored in database 490 during step704.

Once mobile unit 104 has received the path information and determined acurrent location, it may start moving during step 706. In someembodiments, mobile unit 104 may wait to start moving until it hasreceived a ‘start’ command from athlete 102 or trainer 500. This ‘start’command could be implemented using a vocal command that would bereceived by microphone 434, for example. In other embodiments, trainer500 may transmit a ‘start’ command from computer 482 or even a separateremote of some kind.

As mobile unit 104 moves, its current location is determined during step708. The location of mobile unit 104 may be determined using variousmethods. In some embodiments, the absolute location of mobile unit 104may be determined using a GPS system, when mobile unit 104 includes GPScapabilities. In other embodiments, the location of mobile unit 104 withrespect to practice field 106 may be determined using various methods,including, as previously discussed, a network of RFID tags associatedwith practice field 106, which may transmit location information signalsthat may be received by mobile unit 104. Additionally, the relativelocation of mobile unit 104 with respect to a starting point may beinferred by keeping track of how far it has traveled as well as anyturns it has taken. Preferably, the location of mobile unit 104 isstored in database 490 during step 710. In other embodiments, mobileunit 104 may send the location information to computer 482 or to anotherdevice such as a remote database during step 710.

Presumably, athlete 102 may chase mobile unit 104 once mobile unit 104is moving, as seen in FIGS. 1 and 2. During step 712, mobile unit 104may receive various information about athlete 102, especially withrespect to the location and/or speed of athlete 102, as previouslydiscussed in reference to sensor system 492. Information regarding thelocation of athlete 102 is preferably stored in a similar manner to theinformation regarding the location of mobile unit 104, during step 710.

In some embodiments, additional information associated with athlete 102may be received and/or stored. For example, an athlete's current speed,trajectory or other information may also be determined and stored. In apreferred embodiment, only the location of athlete 102, and the time theinformation is received may be necessary. From this location and timeinformation, speeds, accelerations and other information may be latercalculated and analyzed.

After step 712, mobile unit 104 preferably determines if it hascompleted the training path during step 714. If not, it continues movingalong the training path during step 716, and proceeds to step 708 onceagain. Generally, this sequence of determining the locations of mobileunit 104 and athlete 102, as well as storing the location and/or otherinformation, progresses very rapidly. In some embodiments, mobile unit104 may cycle through steps 708, 710, 712, 714 and 716 hundreds or eventhousands of times a second. In this sense, athlete 102 and mobile unit104 may function as a telemetry system that is rapidly transmitting andreceiving information in an attempt to precisely and accurately measureand record an athlete's motion during a training session.

When mobile unit 104 has finally completed the training path, it willpreferably proceed from step 714 to step 718, where it may send all theinformation that it has gathered during the training session to computer482. In other embodiments, the information may be viewed using displaydevice 472 of mobile unit 104. This compiled information may be used bya trainer or coach to study the performance of athlete 102 and perhapsmake adjustments to the training regiment.

In an alternative embodiment, mobile unit 104 may include provisions forautomatically adjusting its speed along a path. FIG. 8 is an example ofa training session where mobile unit 104 is so far ahead of athlete 102that athlete 102 is running along straight path segment 804 to catch up,rather than performing lateral movements and turns along diagonal pathsegment 802 of path 800.

FIG. 9 is a flow chart of an alternative embodiment of a process ormethod associated with mobile unit 104, where mobile unit 104 mayautomatically adjust its speed depending on the distance between athlete102 and mobile unit 104. Generally, mobile unit 104 proceeds, asdiscussed in the previous embodiment, through steps 702, 704, 706, 708,710 and 712 until step 714. At this point, if mobile unit 104 has notreached the end of the training path, mobile unit 104 may proceed tostep 902. During step 902, mobile unit 104 may evaluate its distancefrom athlete 102. If the athlete is close, mobile unit 104 may proceedto step 904, where mobile unit 104 increases its speed in order to keepfrom being caught by athlete 102. The term ‘close’ here may refer to apredefined distance. Otherwise, mobile unit 104 may proceed to step 906.During step 906, mobile unit 104 decreases its speed to prevent athlete102 from lagging too far behind. After either step 904 or 906, mobileunit 104 may proceed to step 716 and then to step 708. As with theprevious embodiment, mobile unit 104 may cycle through steps 708, 710,712, 714, 902, 904, 906 and 716 until the end of the training path isreached. Generally, this sequence of determining the locations of mobileunit 104 and athlete 102, as well as storing the location and/orinformation, progresses very rapidly, as previously discussed.

When mobile unit 104 has finally completed the training path, it willpreferably proceed from step 714 to step 718, where it may send all theinformation that it has gathered during the training session to computer482. In other embodiments, the information may be viewed using displaydevice 472 of mobile unit 104.

Referring back to FIG. 8, path 810 represents the path taken by athlete102 when mobile unit 104 has slowed down enough to keep athlete 102close behind. Path 810 is preferably similar to path 800, which mayfacilitate in training athlete 102 in sharp turning.

FIG. 10 is a preferred embodiment of performance report 1000 that may becompiled using information gathered by mobile unit 104 during thetraining session. Report 1000 may be processed by trainer 500 usingcomputer 482, or in some embodiments, report 1000 may be processeddirectly by mobile unit 104. Report 1000 includes several athleticskills under column 1002 that may be evaluated via the training sessionwith mobile unit 104. Examples of athletic skills seen in thisembodiment include: top linear speed, top linear acceleration, toplateral speed, top left turning speed, top right turning speed as wellas other athletic skills. The reported values, shown in column 1004,allow trainer 500 to evaluate athlete 102 with respect to variousathletic skills.

In some embodiments, mobile unit 104 may include provisions fordynamically choosing a training path. In other words, mobile unit 104may select its own training path that depends on dynamic conditions suchas the current location of athlete 102 and/or boundaries of practicefield 106. For example, in some cases, mobile unit 104 may randomlygenerate a training path that begins at its current location alongpractice field 106. Before mobile unit 104 proceeds, it may be importantto determine if executing the currently selected training path wouldlead if off of practice field 106. Just as a real football player wouldknow to stay in bounds during a game, mobile unit 104 must be able toexecute self selected training paths without going out of bounds inorder to realistically train athlete 102.

FIG. 11 is a flow diagram of a preferred embodiment of a method orprocess used by mobile unit 104 to choose and execute a training path onthe basis of dynamic conditions such as athlete location and boundarylocations. During step 1102, mobile unit 104 preferably creates a newtraining path. Referring to FIG. 12, step 1102 of selecting a newtraining path may be further broken down into sub-steps. Beginning withsub-step 1202 of step 1102, mobile unit 104 may determine its ownlocation and the location of athlete 102 using any of the methodspreviously discussed. Following this, during sub-step 1204, mobile unit104 may generate a new training path. This new training path may begenerated using any process, including processes that generatesubstantially random training paths.

At this point, the training path must be further analyzed to determineif the path is permitted by a predetermined set of dynamic conditions.Two such dynamic conditions have been previously discussed. Onecondition, illustrated in FIG. 13, is that mobile unit 104 should alwaysmove in a direction that is ‘away from’ athlete 102. Because mobile unit104 is training athlete 102 to chase, it would be an undesirableconsequence for mobile unit 104 to execute a training path that leadsdirectly back to athlete 102. Therefore, in some embodiments, the firstdynamic condition may be a rule that requires mobile unit 104 to choosea new training path that has a first trajectory aimed away from athlete102.

Following sub-step 1204, mobile unit 104 proceeds to sub-step 1206 ofdetermining if the direction of the new path is away from the athlete.If the new training path meets this dynamic condition of being directedaway from athlete 102, mobile unit 104 may proceed to sub-step 1208,otherwise mobile unit 104 proceeds back to sub-step 1204, where a newtraining path is generated. Generally, mobile unit 104 may loop throughsteps 1204 and 1206 until it selects a path that meets the requiredcondition of moving away from athlete 102.

In FIG. 13, mobile unit 104 is disposed at end point 1302 of firsttraining path 1304, with athlete 102 close behind moving along secondpath 1306. In order to move away from athlete 102, mobile unit 104 willpreferably only consider a new training path directed along a 180 degreearc 1308 from first axis 1310. In this embodiment, first axis 1310 isperpendicular to second axis 1312 that is directed away from athlete102. In other words, mobile unit 104 may only consider moving indirections in front of first axis 1310 and may not consider moving indirections behind first axis 1310. Alternatively, mobile unit 104 couldalso be programmed to consider only new training paths with firsttrajectories along 90 degree arc 1320 as well as any other arc ofdirections.

Once mobile unit 104 has proceeded to sub-step 1208, it may check to seeif executing the currently generated training path would move mobileunit 104 out of the boundaries associated with practice field 106.Mobile unit 104 may determine the location of predefined boundariesusing various methods. In one embodiment, the boundaries of practicefield 106 may be defined using first boundary marker 120, secondboundary marker 121, third boundary marker 122 and fourth boundarymarker 123, as seen in FIGS. 1 and 2. These boundary markers maytransmit radio signals or other types of signals that communicate withmobile unit 104. In other embodiments, mobile unit 104 may include apredefined map of practice field 106. Therefore, knowing the currentlocation of mobile unit 104 on practice field 106 allows mobile unit 104to determine the relative locations of the boundaries.

In cases where the currently generated path crosses over one or moreboundaries of practice field 106, it may proceed to back sub-step 1204of generating a new training path. Thus, steps 1204, 1206 and 1208 mayproceed until a new training path has been selected that meets thenecessary dynamic conditions. If the currently generated training pathdoes not cross over the boundaries of practice field 106, mobile unit104 may proceed to a final sub-step 1210, where the currently generatedpath may be selected for execution by mobile unit 104.

FIG. 14 illustrates a case where mobile unit 104 must select between twopossible training paths on the basis of boundary conditions. In thisembodiment, first path 1402 is directed across field boundary 1404,while second path 1406 is disposed entirely within practice field 106and does not cross field boundary 1404. Therefore, in this embodiment,mobile unit 104 must select second path 1406 in order to avoid crossingfield boundary 1404.

The consideration of boundaries and that requirement that mobile unit104 should always move away from athlete 102 are only meant to beexemplary conditions for selecting training paths. In other embodiments,other conditions may be used to determine the subsequent paths taken bymobile unit 104 during a practice session. In some embodiments,boundaries may be ignored, and mobile unit 104 may move in anydirection.

Referring back to FIG. 11, once mobile unit 104 has created and selecteda new training path during step 1102, mobile unit 104 may then proceedto execute this new training path and start moving during step 1104. Ifthe training session has just started, mobile unit 104 may wait to startmoving until it has received a ‘start’ command from athlete 102 ortrainer 500. This ‘start’ command could be implemented using a vocalcommand that would be received by microphone 434. In other embodiments,trainer 500 may transmit a ‘start’ command from computer 482 or even aseparate remote of some kind.

As mobile unit 104 moves, its current location is determined during step1106. The location of mobile unit 104 may be determined using any of thepreviously described methods. Preferably, the location of mobile unit104 may stored in database 490 during step 1108. In other embodiments,mobile unit 104 may send the location information to computer 482 or toanother device such as a remote database.

Presumably, athlete 102 may chase mobile unit 104 once mobile unit 104is moving, as seen in FIGS. 1 and 2. During step 1110, mobile unit 104may receive various information about athlete 102, especially withrespect to the location and/or speed of athlete 102, as previouslydiscussed in reference to sensor system 492. Information regarding thelocation of athlete 102 is preferably stored in a similar manner to theinformation regarding the location of mobile unit 104, during step 1108.

In some embodiments, additional information associated with athlete 102may be received and/or stored. For example, an athlete's current speed,trajectory or other information may also be determined and stored. In apreferred embodiment, only the location of athlete 102, and the time theinformation was received may be necessary. From this location and timeinformation, speeds, accelerations and other information may be latercalculated and analyzed.

Following step 1110, mobile unit 104 may proceed to step 1112. At thispoint, mobile unit 104 may determine if it has reached the end of thenew training path. If mobile unit 104 has not reached the end of the newtraining path, it may proceed to step 1116 and continue moving along thenew training path. As with the previous embodiments, mobile unit 104 mayproceed through a rapid cycle of steps 1106, 1108, 1110, 1112 and 1116until it reaches the end of the new training path. Additionally, in someembodiments, mobile unit 104 may adjust its speed depending on how farmobile unit 104 is from athlete 102. This may be achieved by methods orprocesses discussed in previous embodiments.

When mobile unit 104 has reached the end of the new training path,during step 1112, it may proceed to step 1118. During step 1118, mobileunit determines if a control signal has been sent to stop the trainingsession. This control signal may be sent by athlete 102, trainer 500 oranyone else. Furthermore, this control signal may be an electronicsignal, a vocal signal or any other kind of signal. If a control signalhas not been received, mobile unit 104 will proceed to step 1102 whereit will choose a new training path on the basis of dynamic conditions,as previously discussed. Mobile unit 104 may then cycle through steps1104,1106,1108,1110, 1112,1116 and 1118 indefinitely. Generally, thisprocess continues until a control signal has been received to stop thetraining session at step 1118. At this point, mobile unit 104 mayproceed to step 1120 and send information about athlete 102 to computer482. In some embodiments, a performance report may be generated, duringor after step 1120, that is similar to performance report 1000 of FIG.10.

In some embodiments, mobile unit 104 may include provisions for adaptingits movement based on more complicated dynamic conditions such as theathlete's overall performance. In some embodiments, mobile unit 104 may‘learn’ an athlete's strengths and/or weaknesses and adjust the currenttraining path to stress various athletic skills such as linear speed,left/right turning speed, linear acceleration and other similar athleticskills. The term ‘learn’ refers to general computational processesassociated with pattern recognition, as well as other processesassociated with known algorithms used in the field of machine learning.Generally, any type of learning algorithms may be used, includingalgorithms associated with the following types of learning: supervisedlearning, unsupervised learning, semi-supervised learning, reinforcementlearning, transduction and learning to learn algorithms.

FIG. 15 is a flow chart of a preferred embodiment of a method or processassociated with mobile unit 104. During a first step 1502, mobile unit104 preferably creates and executes an initial training path. Step 1502may be performed according to any of the processes or methods previouslydiscussed with respect to creating and selecting a training path. Insome embodiments, the initial training path may not be created by mobileunit 104, but instead designed and submitted to mobile unit 104 by atrainer, coach or the athlete. The training path may be any length andlast any amount of time. Preferably, the training path lasts long enoughand includes several types of motions associated with various athleticskills, so that mobile unit 104 has enough data to analyze theperformance of athlete 102.

During a second step 1504, mobile unit 104 preferably monitors athlete102. This step may be similar to, and comprise many steps such as thosediscussed in the previous embodiments with respect to determining theathlete's location, speed, the location of mobile unit 104 as well asstoring this information. In particular, second step 1504 mayincorporate all or some of steps 1106, 1108, 1110, 1112 and 1116,associated with a previous embodiment and illustrated in FIG. 11.

At a predetermined point in the training session, mobile unit 104preferably proceeds to third step 1506. During this step 1506, mobileunit 104 may analyze some or all of the data associated with the motionof athlete 102. For example, mobile unit 104 may determine the toplinear speed, top lateral speed, as well as top linear and lateralaccelerations achieved by athlete 102. In some embodiments, mobile unit104 may further process this information using various types of patternrecognition algorithms as are commonly known in the field of machinelearning, including, but not limited to clustering algorithms, neuralnetwork algorithms, genetic algorithms, linear discriminant algorithms,Monet Carlo algorithms, Markov Chain algorithms, as well as other typesof algorithms.

FIG. 16 is a flow chart of a preferred embodiment of the sub-processesassociated with third step 1506. During sub-step 1602, the performancesof athlete 102 with respect to each different athletic skill may bedetermined. In other words, the top linear speed, top turning speed andthe top linear acceleration of athlete 102 may be determined, as well asresults for other athletic skills. Following sub-step 1602, mobile unit104 may proceed to sub-step 1604.

Preferably, during sub-step 1604, the results of athlete 102 associatedwith different athletic skills are ranked. In some embodiments, thisranking may be relative. In other words, mobile unit 104 may determinewhich athletic skills athlete 102 is better at and which athletic skillsathlete 102 is worse at, when considering only the performance resultsof athlete 102. For example, if athlete 102 has a right turning speed of7 meters per second and a left turning speed of 8 meters per second,mobile unit 104 may rank the athlete's performance in right turningspeed as better than the performance in left turning speed. In thiscase, mobile unit 104 preferably moves to from sub-step 1604 sub-step1606.

In other embodiments, mobile unit 104 may include a set ofpre-programmed values that may be compared with the results achieved byathlete 102. For example, a trainer or coach may want athlete 102 to beable to run a minimum of 8 meters per second, or 100 meters in 10seconds. Therefore, mobile unit 104 may use this information to rank thelinear speed of an athlete depending on how the athlete's linear speedcompares with the linear speed expected by the coach. In this case,mobile unit 104 preferably proceeds from sub-step 1604 to sub-step 1608.

Finally, mobile unit 104 preferably proceeds to sub-step 1610 by way ofeither sub-step 1606 or sub-step 1608. During sub-step 1610, mobile unit104 preferably selects one or more of the weaknesses of athlete 102,based on either relative or absolute ranking of the results for eachathletic skill.

Referring back to FIG. 15, mobile unit 104 may proceed to fourth step1508, following third step 1506. During fourth step 1508, mobile unit104 may create a new training path based on one or more of theweaknesses of athlete 102.

FIG. 17 is a preferred embodiment of mobile unit 104 once it hascompleted first training path 1702 and determined one or more weaknessesof athlete 102 as athlete 102 moves along chasing path 1703. Second path1704, third path 1706 and fourth path 1708 represent possible trainingpaths that may be selected by mobile unit 104. In this embodiment,second path 1704 includes left banking portion 1705, and thereforesecond path 1704 may be useful in training an athlete with poor leftbanking speed. Third path 1706 is a straight linear path, and thereforemay be most useful in training an athlete with poor linear speed. Fourthpath 1708 includes short lateral portions 1709, and therefore may beuseful in training an athlete with poor lateral speed and/or turningspeed.

In another embodiment, seen in FIG. 18, mobile unit 104 may select amore sophisticated training path to stress the weaknesses of athlete102. In this embodiment, future training path 1802 preferably includesfirst linear portion 1804, second linear portion 1806 and third linearportion 1808, as well as lateral portion 1810 and banking portion 1812.Path 1802 may be useful in training an athlete with deficiencies inlinear speed and banking speed.

Preferably, mobile unit 104 continues to learn the strengths andweaknesses of athlete 102 during the entire training session. In someembodiments, mobile unit 104 may generate additional training paths,without end, with each training path based on deficiencies learned bymonitoring athlete on previous paths. For example, in FIG. 19, mobileunit 104 may start with first path 1902, that is generated randomly.Following this, mobile unit 104 learns the weaknesses of athlete 102,using the methods and processes described in earlier embodiments, andgenerates second path 1904 to stress these weaknesses. Once mobile unit104 has reached the end of second path 1904, it may re-evaluate theperformance of athlete 102 and determine a next training path 1906, tostress weaknesses learned during execution of first path 1902 and secondpath 1904.

In an alternative embodiment, mobile unit 104 may be configured to chaseathlete 102, rather than be chased by athlete 102. In such embodiments,mobile unit 104 will not predetermine possible training paths or receivea fixed training path, but rather will adjust its motion according tothe motions of athlete 102.

In the previous embodiments, mobile unit 104 included a mobility systemthat was ground-based. The mobility system included wheels or legs, forexample. In some cases, a mobile unit could include an air-basedmobility system. The term ‘air-based mobility system’ refers to anymobility system where the mobile unit does not touch the ground. Thefollowing detailed description refers to various embodiments ofair-based mobility systems associated with a mobile unit for thepurposes of adaptive training.

Throughout the remainder of this detailed description only variations inthe type of mobility system associated with a mobile unit are discussed.It should be understood, however, that each of the mobile unitsdiscussed may be configured with similar provisions as those associatedwith the mobile unit of the previous embodiment. Preferably, each mobileunit of the following embodiments is generally identical to mobile unit104 as discussed with reference to FIG. 4, except for the type ofmobility system being employed. In other words, each mobile unit ispreferably associated with some or all of the cameras, sensors,transmitters/receivers, data bases, remote computers and other similarprovisions associated with mobile unit 104 of the previous embodiment.

Furthermore, throughout the remainder of this detailed description, eachof the following embodiments may also include provisions associated withan athlete similar to those discussed with respect to FIG. 4. Forexample, in each of the following embodiments the athlete may beconfigured with an assortment of sensors, including GPS and RFIDsensors, as well as transmitters and receivers configured to communicatewith the mobile unit. Additionally, each of the practice fieldsdiscussed in the following embodiments may include some, all, or none ofthe provisions previously discussed for facilitating a training system,such as RFID or similar beacons configured to allow the mobile unit todetermine absolute positions of the mobile unit and the athlete on thepractice field.

Using these provisions associated with mobile unit 104, each of themobile units of the following embodiments is preferably configured tomonitor an athlete and adjust the motion of the mobile unit accordinglyin order to adaptively train the athlete, as previously discussed. Inother words, each of the methods for adaptively training an athlete thatwere discussed in the previous embodiments may be applied to the mobileunits of the following embodiments. Furthermore, each of the mobileunits of the following embodiments may include provisions that allow apre-designated training path, that is submitted by a coach or otheruser, to be executed. Each of the mobile units of the followingembodiments may also execute randomized paths and preferably includeprovisions for determining when or if the athlete is nearby in order toavoid getting ‘caught’, as discussed in the previous embodiments.

FIGS. 20-22 are a preferred embodiment of training system 2000. As withthe previous embodiments, training system 2000 preferably includespractice field 2002. For the purposes of clarity, practice field 2002 isshown here as a football field. In other embodiments, practice field2002 could be any other type of practice field, including the variousexamples listed in previous embodiments such as football fields, soccerpitches or fields, lacrosse fields, basketball courts, as well as othertypes of fields and/or courts including any type of open space that maybe used for training purposes.

Preferably, training system 2000 may also include mobile unit 2006configured to train athlete 2004. As with the previous embodiments,training system 2000 is preferably configured so that athlete 2004chases mobile unit 2006 on practice field 2002. Preferably, during thischasing activity, mobile unit 2006 is always moving in a way to avoidbeing caught by athlete 2004. As mobile unit 2006 constantly changesdirection and/or speed, athlete 2004 must adjust to the new directionand speed in an attempt to catch mobile unit 2006. Preferably, mobileunit 2006 moves in a way so that, as athlete 2004 follows mobile unit2006, athlete 2004 is moving linearly, laterally, accelerating anddecelerating over the course of a training session.

In the current embodiment, mobile unit 2006 may be associated withmobility system 2008. Mobility system 2008 may be a cable-based mobilitysystem. Cable-based mobility systems are known in the art and examplesof various types can be found in U.S. Pat. Nos. 6,975,089 and 7,127,998,both of which are incorporated herein by reference in their entirety.
